IGC Proceedings (1977-2023)
With its fast turnover, low cost and high nutrition, lamb production has been developing an important industry of seasonal animal husbandry recently in China. The way of taking lambs from pastoral area and then fattened in farming area is considered to be most effective for lambs can make good use of feeds and climate resources in both farming and pastoral areas. The effects of grazing sainfoin ( Onobrychis viciifolia) stubble fields and adding with green hay on two types of lamb fattening were studied by means of measuring live-weight gains, meat quality and carcass output during 1986-1987, and the …

IGC Proceedings (1977-2023)
Grazing has traditionally been recognized as one of the most important labor-saving means in which herbage can be utilized more economically. However, in Japan, the practice of grazing is declining due to improved farm management - more animals per farm, greater harvest yield per area and higher production performance. Grazing animals tend to be healthier and more productive than animals kept in confinement. In addition, feed cost of raising dairy heifers on high pasture system is reduced by more than 50 % relative to the conventional (dry lot) system and to 65 % when the cost oflabor and facilities are …

Beef Production From Digitaria Eriantha Subsp. Eriantha In A Sub-Tropical Environment, M B. Hardy, N N. Gray
IGC Proceedings (1977-2023)
Digitaria eriantha subsp. eriantha, previously known as D. smutsii (Russel and Smook 1980), is a robust perennial grass adapted to a wide range of soils and climatic conditions. In Australia, the species has performed well on a number of sites with soils ranging from« cracking clays to sandy loams» where rainfall varied between 400 and 1000 mm/annum (Strickland 1987). A similar range of adaptability has been recorded in South Africa (Brockett and Gray 1984, Dannhauser 1985). In cutting trials, D. eriantha yielded between 3500 and 15000 kg of dry matter/ha with annual rainfall of 450 and 1200 mm/annum respectively. The …

Performance Of Three Beef Cow Genotypes When Grazing Sown Pasture At Two Sward Heights, I A. Wright, J R. Jones, T J. Maxwell, A.J F. Russel
IGC Proceedings (1977-2023)
In grassland based systems of animal production, it is important to choose a genotype of animal with production characteristics appropriate to the level of nutrition which can be supplied by the available resources. It is generally recognised that the most economically efficient beef cow systems are those that allow the cows to increase levels of body fat when feed is plentiful or cheap (eg. summer grazing in N. Europe) and to draw on those reserves during periods of feed scarcity or when feed is expensive (eg. winter) (Russel and Broadbent, 1985). The ability of cows to increase body reserves during …

Preweaning growth of beef calves is determined by milk production of the dam and herbage consumption by the calf. These parameters are impacted by quantity of herbage on offer and nutritive quality of the sward. Forage availability and quality are dependent upon species composition and pasture management. In the humid temperate regions, both C3 and C4 species are utilized in grazing programs with traditional grazing management being either continuous or very lax rotations. A grazing study was undertaken to evaluate the preweaning growth of calves and milk production of their dams as impacted by pasture species and intensity of management …

IGC Proceedings (1977-2023)
Two-thirds of the grazing lands in Queensland are on infertile soils, low in organic matter, phosphorus (P) and nitrogen (N) (Weston et al., 1981). Pasture quality is low and average liveweight gain (L WG) of steers on these soils ranges from 0.10 to 0.30 kg/day compared to 0.40 to 0.50 kg/day on more fertile soils. Low herbage production limits carrying capacity to 3-10 ha/animal. The nutritive value can be improved by (i) direct supplementation of animals with N and P, (ii) introduction of a legume together with fertilizer and/or supplement P or (iii) use of heavily fertilized improved grasses ± …
Long-Term Productivity Of Legumes-Based And Pure Grass Pastures In The Eastern Plains Of Colombia, C Lascano, J Estrada
Long-Term Productivity Of Legumes-Based And Pure Grass Pastures In The Eastern Plains Of Colombia, C Lascano, J Estrada
IGC Proceedings (1977-2023)
The savannas of Colombia have acid soils of low fertility, a well defined dry season and an herbaceous native vegetation of low nutritional value (Lascano and Spain, 1986). As a consequence, traditional livestock production is extensive and of low productivity in terms of animal growth and reproduction (Vera and Sere, 1985). An economically attractive alternative to increase cattle production in the savannas of Colombia is through the use of legume-based pastures, provided they are productive and persistent (Nores and Estrada, 1979). This paper presents results on animal production and forage attnbutes of a long-term grazing experiment which includes a grass …

IGC Proceedings (1977-2023)
Grazing is generally the least expensive method of forage utilization ; however, in temperate climates the growing season is relatively short and perennial forages are at peak nutritive value for a relatively short time. Brassica spp. have several characteristics which make them prime candidates for extending the grazing season : (1) they mature rapidly (Guillard and Allinson, 1984); (2) they are frost tolerant and maintain high nutrient value well during cold weather (Jung et al., 1984); and (3) they can be established with minimum tillage techniques (Jung et al., 1984; Koch et al., 1987). The purpose of this study was …

Crop production in various parts of Iran faces significant constraints due to insufficient water availability, which is a major challenge to agricultural productivity. To study the effects of water deficit stress on shoot and root growth characteristics and seed yield of different wheat (Triticum aestivum L.) cultivars, an experiment was conducted using a randomized complete block design with a split-plot arrangement and 3 replications. The main factor was irrigation treatments (full irrigation during the growing season [S1], water withholding after flowering [S2], and water withholding after grain filling at the milk stage [S3]). The secondary factors were wheat cultivars …

IGC Proceedings (1977-2023)
The population of Indonesia is over 145 million and more than 56 % of them earn their living from agriculture (Bi. Stat. Ind., 1983). A major problem in the development of improved animal production has been the shortage of feed and the generally low nutritive value of tropical forages which limit livestock production in Indonesia (Asian Agriculture Survey, 1969). The production of feed of adequate quality for ruminants is an important consideration particularly for small holders. In many situations, nitrogen fixing legume trees can be used as a high protein feed supplement which improves the utilization of grasses and crop …

Forage Production And Nutritive Value Of Leucanea Leucoephala In Southern Puerto Rico, L E. Tergas, R Milton Martinez, A V. Mendez Cruz
IGC Proceedings (1977-2023)
Leucaena leucocephala (L.) is a perennial schrub native to Mexico, Central America and the Caribbean, considered by investigators as a valuable forage legume because of its capacity for high production of digestible forage with a high protein content and tolerance to drought in semiarid regions with annual rainfall less than 1,000 mm (Skerman, 1977). The soil fertility of the semiarid region in southern Puerto Rico is adequate, but rainfall distribution is limiting for forage production and nutritive value. There is a demand for a suitable and inexpensive source of high quality forage to improve the diet of the grazing cattle …

Apparent Digestibility, Dynamics Of Rumen Fermentation And Sites Of Digestion Of Hays Of Leucaena Leucocephala (Lam) De Wit Cv. Peru, N M. Rodreiguez, I Borges
IGC Proceedings (1977-2023)
Protein deficiency, among others, is a common problem for livestock production in tropical regions. The use oflegumes has been suggested as a solution and Leucaena leucocephala has shown a great potential due to its capacity of nitrogen (N) fixation and dry matter (DM) production (NAS, 1984). However, very little is known about its nutritive value regarding its protein-energy balance and the process of digestion. The present work aimed the evaluation of the nutritive value of hays of Leucaena leucocephala cut at two stages of growth, through trials of apparent digestibility, dynamics of rumen fermentation and partition of digestion.

IGC Proceedings (1977-2023)
The nutritive value of forage for ruminants is limited by the digestibility of the complex polysaccharides cellulose and hemicellulose by rumen microbes. In grasses, the polysaccharide fraction of the cell wall is composed largely of polymers of neutral sugars and to a lesser extent uronic acids. Cellulose is a high molecular weight linear polymer of B-1 ➔ 4) linked Dgluco-pyranose units. Hemicellulose is a complex mixture of linear and branched-chain heteropolymers containing xylose, arabmose, mannose, galactose, glucose, and uronic acids (Van Soest, 1982). Lignification of the cell wall is a primary factor limiting the digestion of cell wall polysaccharides. Close …

Feed Evaluation Using Mobile Dacron Bags And Influences Of The Diet Composition, H Anzola, F N. Owens
IGC Proceedings (1977-2023)
The Mobile Nylon Bag (MNB) technique has been used successfully in protein nutrition studies with swine (Sauer et al., 1983) to determine amino acid availability from protein in specific feedstuffs. Canadian researchers also have tested this technique to predict site of digestion in ruminants (Kirkpatrick and Kennelly, 1987). Differences in small intestinal digestion may explain why animal responses differ to dietary protein sources which have similar ruminal escape values (Owens, 1986). The MNB holds promise to appraise the intestinal availability of undegraded dietary protein though further developmel).t and testing are needed. The objective of this experiment was to examine the …

Sites Of Digestion Of Nitrogen Of Hays Made With The Tropical Legume Neonotonia Wightii, R R. Vera, E A. Pizarro, A Toscano, N M. Rodriguez
IGC Proceedings (1977-2023)
Tropical pasture species are of well-known lower quality than temperate species and there is evidence that some tropical legumes may contain antiquality factors that reduce further their nutritive value. Nonetheless, the nutritive value of Neonotonia wightii is generally moderate to high (Pizarro et al., 1983 ; Ribeiro et al., 1980), although there is little information on the factors that affect its quality, and none on the rate and sites of digestion within the gastrointestinal tract of ruminants. The aim of the work reported here was to examine the effect of age on the chemical composition, apparent digestibility and sites of …

Nutritive Value Of Perennial Ryegrass Swards Grazed By Sheep In Autumn In The Uk, J A. Milne, H Dove, A M. Sibbald
IGC Proceedings (1977-2023)
A knowledge of the nutrient supply from grazed herbage for ewes in the autumn in N. Europe is required to predict the consequences for their subsequent reproductive performance. Herbage intake has been found to be positively related to sward height over this period at low sward heights but there is no information over a wider range of heights, on the amounts of non-ammonia nitrogen (NAN) available for absorption in the small intestine nor on the digestion of organic matter in the rumen. Experiments on frozen or artificially dried herbage harvested in the autumn have given variable results for the amounts …

Comparison Of Laboratory Methods For Estimating Herbage Digestibility, Francoise Riviere, P Maupetit, G Blanchard
IGC Proceedings (1977-2023)
Forages are an important source of nutrients for ruminants and recently interest has been shown in using forages for a greater proportion of the nutrients in ruminant production. The feeding value of forages mainly depends on their digestible organic matter contents. Feeding of forages to animals is the most accurate method of evaluation but such trials are expensive and very slow. Many laboratory procedures have been developped for estimating forage nutritive value. Recently, near infrared reflectance has been developped to provide a fast and reliable alternative method. The aim of the study is to compare laboratory methods of forage evaluation …

Enzymatic Solubility And Other Analytic Parameters Predicting Digestibility In Grasses Of Middling Food Value, J Silva Colomer, M Zarate, J C. Guevara, C Fransinelli
IGC Proceedings (1977-2023)
For a long time, laboratories techniques have been applied to predict "in vivo" digestibility. Among the biological methods, those basing on rumen fluid are the most used in the nutrition laboratories (Osbourn and Siddons, 1980). These techniques, however, present difficulties as the necessity of maintaining rumen-fistulated donor animals, variations in ruminal activity and high cost. For these reasons, the capacity of enzymatic solubility to predict digestibility has been studied in the last few years in different forages : hays, cereal straws, silages and pellets (Aerts et al., 1977 ; Rivero Yeas, 1985), agricultural byproducts (Aerts, 1977; Aguilera and Molina, 1986) …

Use Of Near Infrared Spectroscopy To Assess Nutritional Status Of Cattle Diets On Rangelands, J W. Stuth, E D. Kapes, R K. Lyons
IGC Proceedings (1977-2023)
There are two principal means for assessing the quality of grazing ruminant diets, analysis of extrusa from esophageally fistulated animals or indirect estimates from fecal analysis. Wet chemistry methods are well documented for the former but have proven to be of limited value regarding the latter. It is the purpose of this research to determine the suitability of near infrared spectroscopy (NIRS) for estimating diet crude protein (%) and organic matter digestibility (%) directly from extrusa and indirectly from feces.
Near Infrared Reflectance Spectroscopy As An Analytical Tool For World Agriculture, J S. Shenk
Near Infrared Reflectance Spectroscopy As An Analytical Tool For World Agriculture, J S. Shenk
IGC Proceedings (1977-2023)
Agriculture produces the food and fiber needed for human existence. In the past 100 years, it becames apparent that nutrient content and quantity measurements of feed were necessary in livestock feeding programs. During this 100 year period, scientists developed and refined laboratory reference methods for the industry. However, nutritional evaluation of these products was and still is expensive and time consuming. Near infrared spectroscopy (NIRS) analysis offered the promise of rapid low cost analysis of nutrient composition. This analytical method has the potential to overcome the analytical problems facing world agriculture. First reports of NIRS in the literature occured as …

Monitoring The Nutrition Of Grazing Cattle With Near-Infrared Analysis Of Feces, S W. Coleman, J W. Stuth, J W. Holloway
IGC Proceedings (1977-2023)
The nutrition of grazing animals is difficult to assess because of the difficulty in determining the amount and quality of the ingested forage. Although many techniques have been proposed for sampling the grazed forage, none offer quantitative estimates of diet quality and intake for individual animals in large numbers. The feces excreted by animals contain undigested residues of the diet consumed along with products of animal and microbiological origin. The objective was to determine if near-infrared spectroscopy (NIRS) could be used to developed spectral indices from feces which describe the quantitative and qualitative attributes of the diet over a range …

Thus, the objective of the present work was to evaluate some quality indice of Pennisetum clones obtained by tissues culture.
Changes In The Nutritive Value And In The Nutritive Value Yield /Ha Of Some Fodder Grasses During The First Growing Season, D Ferenc
IGC Proceedings (1977-2023)
In Hungary, and also in the areas with similar geographical and climatic conditions, about 40 - 60 per cent of grass yields per year is harvested from the first growth. For the determination of the optimal harvest time it is very important to know the changes in the nutritive value and volume of the first growth. These changes are influenced by the traits of the different varieties too.

Evaluation Of New Varieties Of Fodder Beet (Majoral And Poly Productiva) As New Summer Forages In Egypt, M S. Nowar, S M. Abd El-Baki, I F. Marie, A A. Zaki
IGC Proceedings (1977-2023)
Interest in fodder beet has increased dramatically in many parts of the world. Owing to its yield during summer season in Egypt, time during which shortage of green and succulent forage occurs, interest in its cultivation started early (Ghoneim, 1967 and Abou El-Hassan et al., 1971). Fodder beet has improved cows condition and milk yield and quality (Kocisova, 1976; Burckhardt, 1979; De Brabander et al., 1981 and Pearce, 1983). Fodder beet can considerably increase the farm total energy production. However, to grow it successfully the farmer must have an « arable» mentality (Pearce, 1983). The present research was conducted to …

Accumulation Of Solar Energy By Plants And Energetic Nutritive Value Of Tall Fescue (Festuca Arundinacea Schreb.) At Different Cutting Frequencies, V P. Spasov, D S. Kornyshev
IGC Proceedings (1977-2023)
The prevailing approach for developing fodder base in the North-Western economic region of the USSR is grass feed production. So, choosing plants which should maximize the accumulation of solar energy and provide high yields of quality satisfying cattle requirements is of exclusive importance. Our many year studies of different perennial grasses showed that tall fescue is one of the best to use solar energy in the given conditions of environment. So the experiment was carried out in 1979-1986 with the aim of determining solar energy accumulation and energetic nutritive value of this crop at different cutting frequencies.
